R. PERRY BICYCLE BOAT Filed Sept. 2, 1941 Patented June 23, 1942 UNITED STATES PATENT OFFIQE 1 Claim.

This invention relates to improvements in bicycle boats and has for its object to provide a simple and efficient means oftravel on water.

The invention consists of the novel construction and arrangement of the parts and combination of parts set forth in the following specification and pointed out in detail in the appended claim.

In the accompanying drawing:

Figure 1 is a plan view of my invention.

Figure 2 is a side elevation of Figure 1.

Figure 3 is a section on the line 3-3 of Figure 2.

Figure 4 is a vertical longitudinal section of the sprocket wheel and hub.

Figure 5 is an end View of the sprocket wheel and hub.

Figure 6 is an elevation of one of the paddle wheels mounted on the shaft, the latter being broken away.

Referring to the accompanying drawing forming part of this specification, and in which'like reference numerals designate like parts throughout the several views thereof, I designates the floats which are hollow and rest on the water. These floats I are connected by the uprights 2 and 3 which hold the floats in their relative position, and are connected to the floats at 4 and 5. These uprights 2 and 3, are connected at their uuper ends by a rod 6 and'two downwardly converging rods I, in the lower ends ofwhich latter is mounted a sprocket wheel 8 operated by the pedals 9. Extending across between the floats I, near the front end thereof, is a shaft I0 secured thereto in'the plates II. Revolubly mounted on the said shaft I0 are two sets of paddle wheels I2 and a sprocket wheel I3. The paddle wheels I2 each have a square boss I4 on the side adjacent the sprocket wheel I3 which fit into a square socket I5 on each end of the hub of the sprocket wheel I3 which causes them to revolve with the sprocket-wheel I3. A collar IB is rigidly secured to the shaft II] on the outside of the paddle wheels to hold them in their proper position on the shaft III. A sprocket chain I'I connects the sprocket wheels 8 and I3 so that when the pedals 9 are operated the paddles will be turned causing the floats to move forward or backward as desired. Revolubly mounted in the upright 3 is a shaft I8 having a rudder I9 rigidly secured to its lower end and handle bars 20 secured to its upper end by means of which the rudder I9 is operated to steer the boat.

Having thus described my invention what I claim is:

A bicycle boat comprising two floats, a frame connecting said two floats, a sprocket-wheel mounted in said frame, pedals secured to said sprocket-wheel, a shaft connecting said two floats near the front end thereof, a sprocketwheel revolubly mounted on said shaft and having square sockets in opposite ends thereof, two

paddle wheels revolubly mounted on said shaft each having a square boss on one end to fit into the square socket of the sprocket-wheel hub,
